Optical Flux Lattices for Ultracold Atomic Gases
arXiv:1101.2382 · doi:10.1103/PhysRevLett.106.175301
Abstract
We show that simple laser configurations can give rise to "optical flux lattices", in which optically dressed atoms experience a periodic effective magnetic flux with high mean density. These potentials lead to narrow energy bands with non-zero Chern number. Optical flux lattices will greatly facilitate the achievement of the quantum Hall regime for ultracold atomic gases.
